(Brian Maffly | The Salt Lake Tribune) Alta Ski Area general manager Mike Maughan explains the alignment for a proposed tram up Mount Baldy, one of the Central Wasatch’s most iconic peaks at the top of Utah’s Little Cottonwood Canyon. Alta says the lift would be needed to get ski patrollers on the mountain to control its many avalanche paths. But some skiers and environmentalists are pushing back, arguing Alta’s real goal is to expand its footprint in the increasingly crowded canyon.
